Challenges and opportunities for the diverse substrates of SPOP E3 ubiquitin ligase in cancer.
Review in Theranostics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Speckle-type POZ protein (SPOP), a substrate adaptor of the cullin-RING E3 ligase complex, mediates both the degradation and non-degradative ubiquitination of substrates, which are crucial for regulating various biological functions and cellular processes. Dysregulation of SPOP-mediated ubiquitination has been implicated in several cancers. Emerging evidence suggests that SPOP functions as a double-edged sword: acting as a tumor suppressor in prostate cancer (PCa), hepatocellular carcinoma (HCC), and colorectal cancer (CRC), while potentially serving as an oncoprotein in kidney cancer (KC). Therefore, SPOP's role in tumorigenesis appears to be tissue- or context-dependent. Numerous downstream substrates of SPOP have been identified across various cancers, where they regulate carcinogenesis, metabolic reprogramming, cell death, immune evasion, therapy resistance, and tumor microenvironment (TME) remodeling. However, the definitive role of SPOP in these cancers requires further investigation. A comprehensive understanding of the molecular mechanisms of SPOP in different cancer types will provide new insights into its function in oncogenesis, potentially advancing anti-cancer drug development. Here, we summarize the latest findings on SPOP's functions and structural features, its regulatory mechanisms, the roles of its substrates in various cancers, and SPOP-targeting strategies.
